What is Unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
Given that Coal mines have shafts that can be as much as 7³ feet deep.
We need to find about how many feet deep into the Earth's crust are these shafts.
From the given it is 7³ feet deep.
So let us find the value of 7³
7×7×7
49×7
Forty nine times of seven
343
Three hundred and forty three.
So the coal mines is 343 feet deep into the Earth's crust are these shafts.
Hence, the coal mines is 343 feet deep into the Earth's crust are these shafts.

Give the domain and range of each relationship. Determine whether or not each relationship is a function.
Answer:
Domain={2,5,8}
Range={1,3,6}
Function: YES
Step-by-step explanation:
The Domain of a Function
Is the set of values the input variable x takes.
Range of a Function
It's the set of values the output function takes when x moves into the function's domain.
A function is a relation between an input and an output set of values with the condition that every element in the domain relates only with one element in the range.
Following the definitions above, the domain of the relationship is the set of input values:
Domain={2,5,8}
The range is the set of output values:
Range={1,3,6}
Since each element in the input set is related only to one element in the range, the given relationship is a function.
Answers:
Domain={2,5,8}
Range={1,3,6}
Function: YES

Sam will take four science tests this quarter. Her scores on three of the tests are shown below.
What does Sam need to score on the fourth test to ensure that she will have an average of 90% for all four tests?
Answer:
98%
Step-by-step explanation:
Test 1 - 83%
Test 2 - 91%
Test 3 - 88%
Test 4 - ?
If we use x to represent Test 4, we can create the following equation:
1/4 (83 + 91 + 88 + x) = 90
We find the average here by adding up the four test scores and dividing by 4.
Proceed to solve it:
1/4 (262 + x) = 90
262 + x = 360
x = 98
Therefore, Sam needs to get a 98% to have and average of 90% on all four tests.

Answer:
A. 14ft
Step-by-step explanation:
First get the cones volume formula v=(3.14*r^2*h)/3
Second find the radius which is 1/2 the diameter.
Third plug in given and solve 366= (3.14*5^2*h)/3
366*3=3*(3.14*25*h)/3

How much money will each boy have on the day that the boys have the same amount of money?
$11.20
$30.00
$2.00
$16.00
The boys have $16 on 11th day.
What is Graph?The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.
Following the creation of a research question, data is continuously gathered through observation. The information is subsequently arranged, condensed, categorised, and visually portrayed.
In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.
Usually, data that varies over time is represented with a line graph.
Given:
Daryll is given $30 and spends $1.25 per day on basketball cards.
Larry is given $2 and saves $1.25 per day.
So, to find the same day for both from the graph.
We have to focus on where the lines for two persons intersects, it will the on same day how much money they have.
Hence, the boys have $16 on 11th day.
